Speed limiter
This option allows for the adjustment of the factory speed limiter. Most 5.9L Cummins trucks have a
106 MPH speed limiter from the factory. The limiter can be adjusted from 50 MPH to 200 MPH. This
option can only be adjusted during the Install Download process.
rev limiter
This option allows for the adjustment of the factory rev limiter. Most 5.9L Cummins trucks have a
3500 RPM rev limiter from the factory. The limiter can be adjusted from 3000 RPM to 5000 RPM. This
option can only be adjusted during the Install Download process.
Torque Management (automatic Transmission Only)
This option allows for the disabling of the vehicles torque management for those equipped with
automatic transmissions. This is recommend for those running standalone aftermarket TCM/trans-
mission packages but will also slightly improve throttle response on a stock truck.
nOTE:
By turning the torque management OFF, the PRNDL display will be lost as well as the reverse lights.
Tire Size calibration
This option allows for the re-calibration of the factory speedometer to adjust for non-stock sized
tires. For the most accurate speedometer reading when using non-stock sized tires, it is best to
measure the diameter of the tire using a tape measure rather than going by the printed tire size. In
additon, using a GPS is a great way to dial in your factory speedometer. Entering a larger tire size
will cause the factory speedometer to read higher while entering a smaller tire size will cause the
factory speedometer to read lower. The tire size can be adjusted from 24” to 42”. This option only
takes a few seconds to change and can be adjusted at any time from the Tire Size Calibration menu.
Keyed ignition Source location
Although it is possible to manually power up the Mini Maxx without using a keyed ignition source,
it can sometimes create communication issues between the Mini Maxx and the vehicles ECM. To
eliminate these problems, we highly recommend tapping into a 12V keyed ignition source to supply
power to the Mini Maxx only when the key is in the ON position and the vehicles ECM is online.
Below you will find a commonly used 12V keyed ignition source for your vehicle:
2006-2007 5.9l - fUSE nUMBEr 30
Always tap into the
cold
side of the fuse. On the
2006 - 2007 5.9L Cummins, the
cold
side is towards
the drivers side of the vehicle.
2003 - 2005 5.9l - fUSE nUMBEr 50
